IMPULSE:
When a force acts on a body for a very short time, the product of the force and the time for which the force acts, is called the impulse or impulse of force".
State Gauss's law. The total flux of the electric field E over whichever closed surface is equal to 1/ε o times the net charge enclosed by the surface. That is φ = q / ε
